  If your Greenlee Power Pump develops little pressure, it could be due to several reasons. Check the oil level and add oil if necessary. A clogged intake screen can also cause low pressure; clean or replace it. Additionally, a faulty low-pressure relief valve or issues within the low-pressure system itself could be the cause. Consider replacing the valve or repairing the low-pressure system.

  If your Greenlee Power Pump develops substantial pressure but doesn’t complete the hydraulic operation, a few things could be wrong. A faulty high-pressure relief valve could be the culprit, so consider replacing it. A sticking plunger could also be the issue; in this case, replace the plunger and bushing. Also, check for leaking balls and refinish the seats or replace the balls if needed.

  If you notice erratic pressure buildup in your Greenlee Power Pump, there are a few potential causes. A sticking low-pressure plunger might be the issue, so try replacing it. Also, air or dirt in the hydraulic system can lead to erratic pressure. If that's the case, refer to “Purging (Bleeding) Air from the System” or “Draining and Flushing the System.”

How to troubleshoot Greenlee Power Pump when motor does not run?

  Dr. Jennifer CardenasAug 22, 2025
  If the Greenlee Power Pump motor does not run, it may be due to low voltage or no power at the outlet. Check the voltage at the power supply, referring to the “Specifications” section of the manual for required voltage. Another cause could be a faulty relay, which would require replacement. Alternatively, the motor itself might be faulty, needing repair or replacement.
